Abstract

Apparatuses and methodologies are described that facilitate packet aware scheduling are provided. In some embodiments, if all of the information of a packet cannot be scheduled in a single transmission period, additional resources may be assigned to transmission of the contents of the packet based upon latency requirements and/or transmission constraints of the packet.

Claims

1. An apparatus that facilitates scheduling in a wireless communication environment, comprising:

a scheduler that schedules information obtained from application packets to channel resources; and

a hybrid interface that provides arbitrarily sized chunks of information from the packets and information associated with the application packets.

2. The apparatus of claim 1, wherein the information comprises a remaining number of bits in the application packet.

3. The apparatus of claim 1, wherein the information comprises a timestamp of the application packet.

4. The apparatus of claim 1, wherein the scheduler determines if all information from each of the application packets has been scheduled for a single transmission period and if all of the information from each of the application packets has not been scheduled for the single transmission period, then determining latency constraints and/or transmission constraints for those packets for which not all of the information has been scheduled.

5. The apparatus of claim 1, wherein the scheduler, if there are latency constraints and/or transmission constraints for any application packet, assigns additional resources to schedule transmission of all information bits in the single transmission period for that application packet.

6. The apparatus of claim 1, wherein the scheduler, if there are no latency constraints and/or transmission constraints, schedules transmission of all information bits for the application packet in multiple transmission periods.

7. An electronic device comprising:

a memory that stores a plurality of packets for a user including information to be transmitted over a wireless link, each of the plurality of packets comprising a plurality of bits; and

a processor coupled with the memory, the processor configured to fragment the plurality of packets and to determine an assignment of transmission resources, for transmission over a wireless link, to the user based upon a number of the plurality of information bits.

8. The electronic device of claim 7, further comprising a hybrid interface determines a number of information bits in each packet being fragmented.

9. The electronic device of claim 7, further comprising a scheduler that determines whether to attempt to schedule additional transmission resources to the user based latency constraints of an application of any packet for which not all of the information bits have been scheduled in a single transmission period.

10. The electronic device of claim 7, wherein the processor is further configured to allow transmission of the information bits from a packet in multiple transmission period unless a latency constraint of the application of the packet prevents such transmission.

11. A method for scheduling transmission over a wireless link, comprising:

determining a number of information bits of a plurality of packets to be transmitted over the wireless link for a user; and

scheduling transmission resources for the user based in part upon the number of information bits.

12. The method of claim 11, further comprising, if there are latency constraints and/or transmission constraints, assigning additional resources to schedule transmission for the user in the single transmission period.

13. The method of claim 11, further comprising, if there are no latency constraints and/or transmission constraints for the packet, scheduling transmission for the information of the packet in the multiple transmission periods.
